no headphones or sound from both speakers and headphones

i am running a toshiba satillite a135-s4427 on a 4gb usb stick with persistent changes
the fixes i have attempted were all added to /etc/modprobe.d/alsa-base followed by running alsa force-reload in terminal after each line was entered the prior attempt was changed to a comment and the result added to the line to avoid repeated attempts of the same fix.

i think i have provided all the info fnord0 posted as a prerequisite for asking for assistance. if not please let me know. thanks for your help and patience.

not on headphones which is the current problem. i get sound from my speakers but if i plug in headphones it has no effect. if i enter one of the modprobe options i can get sound out of both but not just from headphones. that is the main limiting factor to spending alot of time working with this distro. i can't stand the silence, and in a public place music gets you stared at.

I had the same problem at first install, then changed over to Root, which I prefer anyways. Has been working for a while now and then just today the sound randomly stopped working. Have done a force-reload of alsa, restarted, and nothing. here is the info requested:

just a thought

it probably won't help but check under modify on the user managment well logged in as root and see if audio is selected. it isn't by default on the user accounts i have made i had to select it. after that i turned up the volume on the kmix sound mixer and i had sound. also i have three different controls for my sound and if any off them is turned down i have no sound playing. i'm new so i don't expect this to fix your issue but heres hoping.
